Thank you so much for this book!
Thanks to those who posted it here!
Thomas J. Barrett was a great man and scientist!
I read this book and understand how people in the US are intelligent and talented!
And I even understand how the United States is a great country!
Moreover, the USA is the greatest country in the world, for its contribution to world science, culture and freedom (yes, these are not empty words!)
I would like my children to live and work in this wonderful country and contribute to it!
Thank you again to the creators of this library!
